About Boon Boon is the professional AI platform built specifically for construction. Founded in the San Francisco Bay Area in 2023 by product and engineering leaders from Samsara, Apple, Google and DoorDash. Boon is backed by leading Silicon Valley venture capitalists. Our AI agents embed directly into existing workflows, from preconstruction estimating to bid management. They automate the repetitive tasks that drain time and margins while surfacing the insights leaders need to make faster and more confident decisions. The result is measurable impact. Teams move faster, bids are submitted sooner, win rates increase, and costs are reduced. Boon enables construction companies to build more, generate more revenue, and grow with confidence. About the Role As a Technical Lead, Software Engineer at Boon, you'll build the product that brings our AI capabilities to construction teams. You'll work across core product features and customer integrations, taking models built by our AI team and turning them into polished experiences that solve real customer problems. Our stack is Ruby on Rails on the backend, React on the frontend, with Python microservices supporting the platform. A significant part of this role is owning customer integrations end-to-end. You'll be the technical point of contact working alongside product managers and solutions engineers to understand customer systems, design integration approaches, and ship solutions. Construction software is often legacy, Windows-only, and lacks modern APIs, so creative problem-solving is essential. You might find yourself building a desktop app to sync files from a customer's local system, or inventing other workarounds to bridge the gap between old and new. This is a hands-on technical leadership role. You'll write code regularly while also driving architecture decisions, coordinating across teams, and mentoring other engineers. You'll work closely with other technical leads and an established engineering team to build a product that delivers real value to construction companies. In this role, you will: Build core product features end-to-end, from backend APIs to frontend UI. Own customer integrations from initial technical discovery through deployment, working alongside product managers and solutions engineers. Serve as the technical point of contact for customers, understanding their systems and requirements while designing integration approaches. Minimum requirements for the role: 7+ years of experience in software engineering with full-stack experience. Strong experience with at least one or two end-to-end full-stack frameworks. You don't need to know Rails and React specifically, but you should be able to ramp up quickly. Demonstrated ability to solve complex, ambiguous problems creatively. We care more about your problem-solving approach than specific technology experience. Experience owning projects end-to-end, from scoping through deployment. Strong collaboration and communication skills. You'll work closely with customers, product managers, and fellow engineers. Experience working with AI coding tools. Our interview process will include using these tools, and you'll use them daily on the job. Ability to learn new systems and technologies quickly, including unfamiliar customer software and integration patterns. Compensation At Boon, we want to attract and retain the best employees and compensate them in a way that appropriately and fairly values their individual contribution to the company. With that in mind, we carefully consider a number of factors to determine the appropriate starting pay for an employee, including their primary work location and an assessment of a candidate’s skills and experience, as well as market demands and internal parity.
